Answer: question 2 b = $3.5992
question 2 c = $48.5892 or you can write $48.58
thats how much i know i dont know about the rest sorry
i will try them out and come back to you if i find an answer
Step-by-step explanation:
1: Solve for either x or y in one of the equations. So x + y = -1 is y = -x -1
2: substitute the new equation in the opposite equation. So x - (-x - 1) = 7
3: distribute the negative. X + x + 1 = 7
4: combine like terms. 2x + 1 = 7
5: solve for x. Subtract 1 on both sides. 2x = 6
6: divide by 2 to get x by itself. X = 3
7: plug the new value of x into one of the ORIGINAL equations. 3 + y = -1
8: solve for y. Subtract 3 on both sides.
Y = -4
9: the solution is written as (x,y) so the solution would be (3, -4)
Answer:
Incorrect.
Step-by-step explanation:
6 + x = 19
Plug in when x = 12
6 + 12 = 19
18 = 19
It is incorrect, so 12 is not a solution.
Answer:
the Prime Factors of 12 are: 2, 2, 3.
Step-by-step explanation:
Therefore 12 = 2 X 2 X 3.
